并行工程要求设计人员在产品的设计决策阶段就考虑其整个生命周期内的全部有关因素。基于模糊集合原理，提出了一个支持并行工程实践的模糊设计折衷决策建模方法，并利用模糊神经网络对该问题进行决策计算，从而找出设计人员最满意的设计方案。
Concurrent engineering requires that designers consider all relevant factors throughout their life cycle at the product design decision-making stage. Based on the principle of fuzzy set theory, a fuzzy design compromise decision-making method is proposed, which supports parallel engineering practice. The fuzzy neural network is used to calculate the decision-making problem so as to find the most satisfactory design scheme.
